Engine fuel oil temperature and pressure control system

The invention discloses an engine fuel oil temperature and pressure control system. The engine fuel oil temperature and pressure control system comprises a machine shell, a fine adjustment limiting plate and an electric heating bar, a foaming layer feeding opening is formed in the middle of the upper end of the machine shell, and a shell heating power supply wiring plug is mounted at one end of the foaming layer feeding opening. The system has the beneficial effects that through a circulation loop pipe, a shut-off valve, a bypass hand valve, an electric heating pipe and a refrigeration pipe, the temperature of fuel oil can be increased and decreased, so that the fuel oil is in a constant-temperature state in various environments, and the accuracy of the fuel oil in a use test is improved; through a microprocessor, a communication module, a port and a storage module, various tested parameters can be recorded and uploaded in real time, the record does not need to be checked manually, and the intelligent operati
